Engineering Selection Recommendations

BAT54C (Diotec Semiconductor): Select this part when sourcing from Diotec inventory is preferred or when the Cut Tape packaging format is required for specific assembly processes. The BAT54C supports a maximum junction temperature of 150°C, providing thermal margin in applications operating near upper temperature limits.

BAT54CTA (Diodes Incorporated): Select this part when ROHS3 compliance certification is required for end-product regulatory adherence. The BAT54CTA carries explicit REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating, suitable for applications with extended storage or humid environment exposure. The maximum junction temperature of 125°C is suitable for standard industrial and commercial temperature ranges. Tape & Reel packaging is standard for high-volume automated assembly operations.

Both parts are active production status and share identical electrical performance specifications, enabling selection based on compliance requirements, packaging format, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can BAT54CTA replace BAT54C in existing circuit designs?

A: Yes. Both parts share identical electrical specifications including reverse voltage (30 V), rectified current (200 mA), forward voltage (1 V @ 100 mA), and reverse recovery time (5 ns). The SOT-23-3 package form factor is identical, enabling direct PCB footprint compatibility.

Q: What is the difference in reverse leakage current between these parts?

A: The BAT54C specifies 2 µA @ 25 V reverse leakage, while the BAT54CTA specifies 4 µA @ 25 V. Both values are within acceptable ranges for Schottky diode applications. Selection depends on circuit sensitivity to leakage current in specific operating conditions.

Q: Are there temperature rating differences between BAT54C and BAT54CTA?

A: Yes. The BAT54C supports a maximum junction temperature of 150°C, while the BAT54CTA supports 125°C. For applications operating continuously near or above 125°C, the BAT54C provides additional thermal margin. For standard industrial temperature ranges (-40°C to 85°C ambient), both parts are equivalent.

Q: What packaging formats are available for each part?

A: The BAT54C is supplied in Cut Tape (CT) and Digi-Reel® formats. The BAT54CTA is supplied in Tape & Reel (TR) format. Selection depends on assembly line equipment compatibility and volume requirements.

Q: Does BAT54CTA have regulatory compliance advantages?

A: Yes. The BAT54CTA is ROHS3 compliant and carries REACH Unaffected status, meeting regulatory requirements for products sold in regions with environmental compliance mandates. The BAT54C lists RoHS status as "Not applicable" and REACH status as "Vendor Undefined."

Q: Are both parts suitable for high-frequency switching applications?

A: Yes. Both parts are classified as Small Signal devices with reverse recovery time of 5 ns, suitable for high-frequency switching applications up to the 200 mA current rating per diode.
